dc.description.abstract
The quality of the free-surface water jet influences Pelton turbine efficiency. Secondary flows resulting from the interior parts of the injector can deform the jet shape. By numerical flow simulations, this work identifies that the secondary flow pattern in a Pelton turbine jet resembles a quadrupole potential flow. This pattern is generated by the wake formation caused by the torpedo ribs. Further, it is demonstrated how streamlining the interior parts reduces the amount of secondary flow in the jet.
